To all whorn, it mdy condemn Be it known that I, EnwARD H. FRIOKEY, a

citizen of" the United States,1 residing at St.

' Louis, Missouri, have invented a certain new and useful Im rovement in Feeding Mechanism for Shred ing-Machines, of which the following is a full, clear, andv exact description, such as will'enable others skilled in the art, to and use the. same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elvational View of my improved feeding device. Fi Z'is a top plan View. Fig. 3 is a lon itu inal sectional View, and Fig. 4 is'a side e evational view as izeenfrorn the side opposite to'that shown in (I i 1.

This invention relates to a new and useful improvement in feeding mechanism for shredding-maehines, being designed articularly for use. in connection with t e wellknown type of Williams machine.

The obj 'ect of the present invention is to control the gap between the feed-rollers located;

at the mouth of the mill, so that said feed-rollers will be spaced apart ,theflpro er distance according to the thickness oft e batch of material entering the machine. With this object in view the invention'consists in the construction, arrangement, and combination driven by a belt of' the severalparts, all as will .be hereinafter described and afterward claims. p

In the drawings, 1' indicates a shredding-- mill of usual construction, said mill being 2. As .usual this mill is provided with cage-bars 3, withwhichco6perate pivoted revolvin hammers.

At the feed end the machine there is a cor rugated feed-roller 4 a triangular bar 5, over I which the I material to'be acted upon by the hammers is fed, and a superposed corrugated ton F. Williams on or. a

given .Serial No. 215,936, he has shown this arrangement of feed-rollers 4 and 6 with the triangular bar 5, and therefore I do not claim the same here. The difference in the present invention and thatforming the subject-matter of said application is that I prefer to corrugate the lower feed-roller 4 and to mount Specification of Letters Patent.
